TECHNICAL FIELD

The present disclosure relates to the field of agricultural devices, and, more particularly, to disease prevention device and related methods.

BACKGROUND

The agricultural industry is a large and robust industry worldwide. To meet worldwide demand for agricultural products, producers utilize numerous methods to maximize production in agricultural crops. For example, one technique includes removing unwanted growth (i.e. soil cultivation) around the base of crops to enhance growth and production. Typically, this is accomplished with the application of herbicide around the base of most crops.

Although there are effective herbicides, there are several drawbacks to their use. Firstly, the adaptation of herbicide resistant “super weeds” has reduced the effectiveness of many herbicides. Secondly, herbicides cannot be applied toward organic fields or directly over non-GMO crops. Thirdly, the application of herbicides may weaken the crop's natural defense, and application to crops prior to harvest may result in crop damage when contacted by spray drift or when absorbed from the soil by the plant's root system.

Another technique is implementation of a robust fertilization program. Although fertilization programs do enhance growth of crops, they can be costly to implement and maintain. Moreover, herbicides cannot be applied toward organic fields or directly over non-GMO crops.

Yet another technique is a robust insecticide program. Of course, this programs provides benefits from evasive insects that harm the crop. Another benefit is the insecticide program may help prevent infection of the crop from disease, such as fungus and bacterial infections.

One example disease is citrus greening, also known as Huanglongbing (HLB) or yellow dragon disease. Citrus greening disease is one of the most serious citrus plant diseases in the world because there is currently no cure. The disease has devastated millions of acres of citrus crops throughout the United States and abroad. Citrus greening disease is spread by a disease-infected insect, the Asian citrus psyllid

The infected insect spreads the disease as it feeds on the leaves and stems of citrus trees. Citrus greening disease is further spread by moving infected plants and plant materials.

The disease has affected the entire US citrus industry, and has been reported in 33 nations worldwide. Infected citrus trees produce fruits that are green, misshapen and bitter, unsuitable for sale as fresh fruit or for juice. Most infected trees die within a few years and have few productive years, if any.

Citrus greening disease is typically managed using insecticides to control the psyllid population. Evidence shows that reducing psyllid populations via insecticide application not only slows the rate of citrus greening disease spread but also reduces severity of the disease once established.

Young trees that produce multiple flushes throughout the year are at greater risk of greening infection than mature trees because of the attraction of adult psyllids to the new flush. Even without the disease, young trees need to be protected for about four years from psyllids and leaf miners to grow optimally. In some approaches, soil-applied systemic insecticides provide long lasting control of psyllids, but the chemicals may be environmentally harmful.

In other approaches, tree covers that enclose a tree to prevent insect infiltration are deployed. These tree cover approaches, however, may suffer from one or more drawbacks. The tree cover may rest its weight against the tree, which can damage foliage and branches of young trees. In some approaches, the tree covers may have a Skelton-like framework that prevents the cover from resting against the foliage, but the framework may provide for a more complicated install.

SUMMARY

Generally, a plant cover device may include an enclosure comprising an upper end, a lower tubular end opposite the upper end, and a medial seam coupling the upper end and the lower tubular end. The upper end may comprise a plurality of panels coupled together to partially define a plant-receiving cavity therein. Each of the plurality of panels may have a major mesh surface, and a panel seam extending along a peripheral edge of the major mesh surface, adjacent panels being coupled together at respective panel seams. The lower tubular end may include a major mesh surface and having a first end and a second end opposite the first end, the first end being coupled to the medial seam. The lower tubular end may also partially define the plant-receiving cavity therein. The enclosure may comprise a curved flexible support carried by the medial seam, and a pole extending vertically from a surface to an apex of the enclosure.

More specifically, each of the plurality of panels may comprise a pentagon-shaped panel. Each of the plurality of panels may comprise a triangle-shaped section, and a rectangle shaped section coupled to the triangle-shaped section. The respective triangle-shaped sections of the plurality of panels may define the apex of the enclosure and an uppermost portion of the plant-receiving cavity.

In some embodiments, the second end of the lower tubular end may comprise a solid section at a lowermost end of the lower tubular end. The solid section may be opaque to visible light radiation and waterproof. The second end of the lower tubular end may comprise a drawstring coupled at a lowermost end of the lower tubular end. The curved flexible support may comprise a loop-shaped support, for example. The curved flexible support may comprise a single piece flexible rod. The medial seam may comprise an annular sleeve, and the curved flexible support may be carried within the annular sleeve. For example, each mesh surface may comprise a plurality of mesh openings, each opening having a diameter of less than 300 μm.

Another aspect is directed to a method of making a plant cover device. The method may include forming an enclosure comprising an upper end, a lower tubular end opposite the upper end, and a medial seam coupling the upper end and the lower tubular end. The upper end may include a plurality of panels coupled together to partially define a plant-receiving cavity therein. Each of the plurality of panels may have a major mesh surface, and a panel seam extending along a peripheral edge of the major mesh surface. Adjacent panels may be coupled together at respective panel seams. The lower tubular end may comprise a major mesh surface and have a first end and a second end opposite the first end, the first end being coupled to the medial seam.

DETAILED DESCRIPTION

The present disclosure will now be described more fully hereinafter with reference to the accompanying drawings, in which several embodiments of the invention are shown. This present disclosure may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the present disclosure to those skilled in the art. Like numbers refer to like elements throughout; prime notation is used to indicate similar elements in alternative embodiments; and base 100 reference numerals are used to indicate similar elements in alternative embodiments.

Young citrus trees are at greater risk than mature trees of infection because of frequent leaf flush (fresh growth) which attracts the psyllid as well as many other pests as the young tree grows. The plant cover system described here may advantageously be used to protect young citrus trees for the first three years and beyond after planting. However, it should be recognized that the cover can also be used on a wide variety, size, and age of fruit trees, ornamentals, vegetables, and the like. It is to be understood that the term “plant” as used herein may include trees. For example, “a plant cover” refers to a cover for trees and other plants.

Referring to FIG. 1 , a first example embodiment of the plant cover system 100 includes a plant cover bag 200 upwardly supported by a vertical support member 300 over a tree 102. The bottom of the bag 200 is closed around the trunk 104 of the tree 102. An optional trunk cover 400 encircles the trunk. A closure 500 closes the bottom of the bag 200 around the trunk 104.

Additional details of the bag 200 are now described with reference to FIGS. 2-6 . The bag 200 has a generally kite shaped exterior perimeter 202 and is formed from a first kite shaped panel 204 and a second kite shaped panel that are joined together along a seam 208 forming the exterior perimeter 202 by a conventional joining mechanism such as using an adhesive, sewing, stapling, or the like.

The seam 208 adds rigidity to the exterior perimeter 202, allowing the exterior perimeter 202 to maintain its kite shape without a separate support frame when suspended over a tree. This allows the midsection of the bag 200 to bulge out around the tree's foliage so that the bag 200 does not rest its weight against the foliage.

An upper section 210 of the bag 200 is generally triangle shaped. A lower section 212 of the bag 200 is generally trapezoid shaped. A bottom end of the bag 200 includes a rim 214 that circumscribes an opening 216 to the bag's interior 218.

A slot 220 interrupts the seam 208, extends vertically from the opening 216, and includes a pair of opposed margins 222 that include cooperatively interlocking parts 224 that can temporarily be joined and separated to increase the size of the opening when installing over a plant. The interlocking joining mechanism for the margins 222 may be a hook and loop type closure such as hook and loop interface, a zipper, or the like. The entire length of the slot 220 may be completely closed to prevent insects from entering through the slot 220.

Referring to FIGS. 5 & 6 , the length of the slot 220 may vary among different examples to accommodate different sizes and shapes of plants and trees. In the example of FIG. 6 , the slot 220 extends from the opening 216 to the upper section 210 of the bag 200 and terminates before reaching the bag's top apex 224. In the example of FIG. 7 , the slot 220 extends from the opening 216 and part of the way to the side apex 226. If the plant being covered is a fruit or vegetable plant, the extended slot 220 can be opened to harvest the fruits or vegetables from the plant and then closed.

The panels 204, 206 form a wall that encloses the interior of the bag 200. The panels 204, 206 may be made at least partially or completely of a mesh material, which provides water permeability and light transmissivity, but prevents intrusion by small insects such as psyllids. The mesh size may be, for example, 50 mesh or 50 by 25 threads per square inch. Such a mesh size will be sufficient to prevent intrusion by psyllids, aphids, white flys, mealy bugs, leaf miners, thrips, grasshoppers, ants, and orange dogs. The bag 200 may also protect the enclosed foliage from frost, hail, and wind damage.

Referring to FIGS. 7-9 a second example embodiment of the bag 200′ includes three kite shaped panels instead of two. In FIGS. 7-9 a prime symbol (′) denotes features corresponding to the previous example. The three kite shaped panels 204′, 205, & 206′ are joined together at the seam 208′ so that the bag has three side vertices 226′. This configuration provides more interior volume than in the first example to accommodate larger plants and trees.

Referring to FIG. 10 , the vertical support member 300 may be inserted into the ground like a stake adjacent to the tree 102 so that it extends vertically alongside and in close proximity to the tree 102. The top end 302 upwardly supports the bag 200, keeping the bag 200 from resting on the tree 102 and suspended above the ground. The top of the tree and the top end 302 are offset by a height H1 to allow the tree 102 to grow within the bag 200. The top apex 224 of the bag 200 is positioned atop the top end 302 of the vertical support member 300. The seam 208 provides enough rigidity to the bag 200 to maintain its kite shape. The opening 216 is closed around the trunk 104 of the tree 102 with the closure 500.

The vertical support member 300 may take on many different forms. In the example shown, the vertical support member is a rod-shaped or tubular stake with a plastic or rubber cap 304 on the top end 302 that prevents the vertical support member from causing wear to the bag 200 when the bag 200 moves in the wind, which could generate holes in the bag 200. In other examples, it may include arms extending horizontally from the stake to support the sides of the bag 200 and produce a support frame.

The closure 500 is a string, belt, band, or the like that circumscribes the bag 200 and can be tightened to close the opening 216. The closure 500 may take many different forms such as a drawstring integrally formed with the bag 200, a separate string or rope that can be tied around the bag, a zip or cable tie, a belt, an elastic band, and the like.

The bag's 200 kite shape provides an advantage over other conventional plant covers. The kite shape makes the bag 200 somewhat form fitting to the shape of a tree. It is skinnier at the bottom and top and bulges in the middle to accommodate branches and foliage. The kite shape also provides room for the tree to grow both taller and wider within the bag 200.

The trunk cover 400 encloses the trunk 104 of the tree by encircling it. The trunk cover 400 may be a conventional tubular tree trunk cover or tree trunk wrap. In the example of FIG. 1 , the trunk cover 400 has plastic tubular construction and extends from the ground up the trunk. The bag's opening 216 is tightened closed against the trunk cover 400 around the trunk 104. The trunk cover 400 may have a reflective exterior surface. The trunk cover 400 may reduce the amount of pesticides that need to be applied to the tree because it will prevent insect damage.

In an exemplary method of covering a plant using the bag, plant foliage is positioned within the bag 200 by lowering the bag 200 over the plant through the opening 216 in the bag 200. The bag is suspended the bag on a stake positioned next to the plant. The stake extends above the top of the plant. The opening is then closed around a stem or trunk of the plant. To make it easier to position the foliage within the bag 200, the slot 220 may be temporarily opened to increase the size of the opening 216. Once the foliage is within the bag, the slot 220 may then be closed.

The bag 200 is easily removable from the plant or tree when no longer needed even though the plant or tree covered might have grown because the slot 220 can be opened during removal. The bag 200 and vertical support member 300 may then be reused. The bag 200 is lightweight and flexible, allowing for efficient storage and/or shipment. When not in use, the bag 200 may be folded or rolled up for storage.

Another example embodiment of the plant cover system 200″ will now be described with reference to FIGS. 11-16 . This example includes a bag 200″ including any of the features already described and a base member 300. The base member 300 is attached to the bag 200″ along a seam 302.

The base member 300 includes an upper surface 304, a lower surface 306 opposite the upper surface 304, and a perimeter 308. The perimeter 308 in the example shown is substantially circular. The perimeter 308 may have different shapes in different examples.

The base member 300 includes an irrigation member 310 configured to provide a mechanism for irrigating a plant within the bag 200″. In the example embodiment shown, the irrigation member 310 includes a tubular wall 312 defining an opening 314 and an interior space 316 extending substantially around the perimeter 308.

The interior space 316 receives an irrigation line 400, such as the example shown in FIG. 16 . The irrigation line 400 is adapted to deliver water to the plant by including openings 402 along its length through which water can escape. Water leaving the irrigation line 400 exits the irrigation member 310 by openings 320 formed in the bottom 306 of the irrigation member 400. In this example the irrigation member 310 is positioned along the perimeter 308 in order to deliver water to the outer reaches of the plant's root system. It is not necessary for the irrigation member 310 to be positioned along the perimeter 308 in every example.

The base member 300 may include a shape maintaining feature for maintaining the shape of the perimeter 308. Such a shape maintaining feature may be attached to the base member about or along the perimeter 308. The shape maintaining feature may include a wire, cable, rope, resilient pole, or the like.

The base member 300 defines an opening 322 through which the base of the plant may be positioned. The opening 322 in the example shown coincides with the seam 302 where the base member 300 and bag 200″ are connected. The shape of the opening 322 is triangular in the example shown, but it may be another shape in other examples.

The base member 300 includes a pair of opposed margins 324 having cooperatively interlocking parts 326 that can temporarily be joined and separated to increase the size of the opening 322. When joined together, the margins 324 define a closed slot 328.

The margins 324 of the base member 300 may be a continuation of the margins 222 of the bag 200″ such that when the margin 222, 324 are separated the slot 328 in the base member 300 and slot in the bag 200″ open together to form a single continuous opening for placing the bag 200″ over a plant.

The base member 300 may be made of water impermeable material such as plastic or the like to maintain water used for irrigation in the vicinity of the plant's roots in order to enhance the efficiency of irrigation. The base member 300 also forms a barrier to insects and other pests around the base of the plant.

The base member 300 may be secured in position around the plant via many mechanisms such as anchoring with stakes and/or by placing soil on top of the perimeter to weigh down the base member 300. Optionally, the top surface 304 of the base member 300 includes a reflective material that provides a mirror like finish. The base member 300 may also be used without the bag as a mechanism for retaining water in the vicinity of the plant's roots.

Referring to FIGS. 17 and 18 , in order to hold the central portion of the base member 300 off the ground, a support frame 500 may be used. The support frame may be made of metal, plastic or the like. The support frame 500 includes two inverted V-shaped stands 502 interconnected by at least one cross beam 504. In use, the bottom of the V-shaped stands 502 is placed in contact with the ground and the weight of the base member 300 is supported by the support frame 500.

Referring now additionally to FIGS. 19-22 , a plant cover device 630 is now described. The plant cover device 630 illustratively includes an enclosure 631, a base 632 coupled to the enclosure, and a support 633 extending vertically from a ground surface to an apex of the enclosure.

In the illustrated embodiment, the support 633 (shown in dashed lines) comprises a simple pole support. In other embodiments, the support 633 may comprise additional lateral supports at a lowermost end adjacent the ground surface. Also, in some embodiments, the support 633 may include lateral arms extending from the uppermost section of the support, creating a canopy of sorts within the enclosure 631, or a dome-shaped portion for supporting the enclosure.

The enclosure 631 illustratively includes a plurality of panels 634 a-634 c coupled together to define a plant-receiving cavity therein. Each of the plurality of panels 634 a-634 c has a “kite-shape”, or in other words, the shape of two adjacent oblique triangles with abutting base sides.

This plant-receiving cavity is perhaps best seen in the embodiment of FIG. 7 . Each of the plurality of panels 634 a-634 c includes a major mesh surface 635 a-635 c, and a seam 636 a-636 c extending along a peripheral edge of the major mesh surface. The mesh openings in the major mesh surface 635 a-635 c are sized to as to prevent penetration by disease carrying insects.

Adjacent panels 634 a-634 c are coupled together at respective seams 636 a-636 c. Each seam 636 a-636 c may comprise one or more of a stitching seam, an adhesive seam, or an integrally formed seam (e.g. attached using a heat gun applied to thermoplastic material).

The enclosure 631 illustratively includes a first fastener 637 adjacent the peripheral edge of a respective panel 634 a-634 c. The first fastener 637 extends along only a portion of the peripheral edge of a respective panel 634 a-634 c (e.g. the illustrated 33%±10). In other embodiments, the first fastener 637 extends along a greater portion of the peripheral edge of a respective panel 634 a-634 c, such as extending along the edge to the corner or along an entire longitudinal side of the enclosure 631.

In the illustrated embodiment, the first fastener 637 comprises opposing hook and loop interfaces on peripheral edges of adjacent panels 634 a-634 c. Of course, in other embodiments, other fastening arrangements can be used on peripheral edges of adjacent panels 634 a-634 c, such as a button and slit interface, or a snap button interface (e.g. riveted snap fastener).

The base 632 illustratively includes a solid major surface 638 extending radially outward, and a second fastener 640 carried by the solid major surface and extending radially from a center to an outer peripheral edge. The base 632 illustratively has a circle-shape. In other embodiments, the base 632 may have other shapes, such as a square, an oval, or a triangle

As perhaps best seen in FIG. 23 , the first fastener 637 and the second fastener 640 are aligned and configured to provide access to the plant-receiving cavity. In particular, the first fastener 637 and the second fastener 640 are directly aligned in an abutting arrangement so that a user can readily open the first fastener 637 and the second fastener 640 in one easy action.

In particular, the plurality of panels 634 a-634 c illustratively defines a trunk receiving opening 641 at a bottom thereof. In some embodiments, the plant cover device 630 includes a tie or tether (see FIGS. 1, 7 & 10 ) configured to bind the lower portion of the enclosure 631 to the truck of the plant. The base 632 illustratively defines a medial opening 642 coupled (e.g. via a seam constituted similarly to the seams 636 a-636 c in the plurality of panels 634 a-634 c) to the trunk receiving opening 641. The second fastener 640 extends from the medial opening 642 to the peripheral edge of the base 632. Each of the trunk receiving opening 641 and the medial opening 642 is illustratively triangle-shaped. In other embodiments, the trunk receiving opening 641 and the medial opening 642 may have other shapes, such as a square, an oval, or a circle.

The base 632 illustratively includes a peripheral passageway 643 carried by the solid major surface 638 and configured to receive a drip line (not shown). The base 632 illustratively includes a plurality of spaced apart notches 644 a-644 c along the peripheral passageway 643 configured to receive respective nozzles from the drip line. As perhaps best seen in FIG. 22 , each of the plurality of spaced apart notches 644 a-644 c comprises opposing first edges 645 a-645 b, and opposing second edges 646 a-646 b. The first and second edges 645 a-645 b, 646 a-646 b are canted with respect to each other. Each second edge 646 a-646 b is substantially perpendicular a (equating to an angle of 75°-105°) to a tangential line of the outer periphery of the base 632.

In some embodiments, the major mesh surface 635 a-635 c of each of the plurality of panels 634 a-634 c may comprise a polyvinyl chloride (PVC) material. The major mesh surface 635 a-635 c of each of the plurality of panels 634 a-634 c may comprise a colored mesh material configured to selectively diffract one or more spectral portions (i.e. frequency ranges) of UV radiation and/or visible light radiation.

Advantageously, the major mesh surface 635 a-635 c of each of the plurality of panels 634 a-634 c can be of different color in order to manipulate or enhance the different spectral portions of the UV spectrum. This is important for keeping a plant in a vegetative state or forcing it into a flowering state in regards to some of the intended uses. As will be appreciated, different spectral portions of the visible light spectrum and the UV spectrum can have wide ranging effects on different plants. For example, for UV radiation,—No exposure produces better growth; Violet—Enhances the color, taste, and aroma of plants Blue—Increases the growth rate of plants; Green—Enhances chlorophyll production and is used as a pigment for proper plant viewing; Yellow—Plants exhibit less growth compared to blue and red light; Red—When combined with blue light it yields more leaves and crops, depending on what is being grown; and Far Red—Speeds up the Phytochrome conversion which reduces the time a plant takes to go into a night-time state. This allows the plant to produce a greater yield. See Klein, R. M., Edsall, P. C., & Gentile, A. C. (1965). Effects of Near Ultraviolet and Green Radiations on Plant Growth. Plant Physiology, 40(5), 903-906; and “Plant Growth”, Chris Thiele, May 29, 2018, Grobo Inc. website, each of which is incorporated by reference in its entirety.

The base 632 illustratively includes a reflective material on an upper surface thereof. In some embodiments, the base 632 may comprise a waterproof material.

Helpfully, this permits for conservation of water in several ways. Firstly, the integrated drip line passageway permits water to be deployed efficiently with minimal evaporation. Second, the reflective upper surface reduces the amount of thermal radiation absorbed by the ground area directly adjacent the root ball, permitting more moisture to be absorbed by the plant and not evaporated. Thirdly, the waterproof barrier also provides an additional water barrier, keeping moisture where it can be used. Also, the base 632 may prevent unintentional drift or runoff of pesticides or fertilizer applied around the base of the plant.

Moreover, the UV diffraction effect from the plurality of panels 634 a-634 c may the improve growth rate of the plant. In particular, Applicant has observed a 20% increase in growth with the application of the plant cover device 630. These enhanced growth benefits are in addition to the disease prevention purpose provided by the enclosure 631, as discussed with regards to the earlier embodiments.
